Specification of Letters Patenta.

Patented Oct. 29, 1907.

Application filed June G 1907. Serial No. 377.612. I

To all whom it may concern: t

Be it known that I, JOHN R. HAMILTON, of St. John, in the Province ofNew Brunswick, Domnion of Canada, .have invented a certain new anduseful Conbination Tool or Utensil; of which the following is aspecification.

Primarily, my device is a combination key ring and v dition as notmaterially to augment its bulkiness, a rule,

a pencil sharpener, a nail file, a nail cleaner, a tack puller, a screwdriver, and an envelop opener.

In the accompanyng drawing, ,which constitutes a part of thisapplication, I illustrate my device in preferred form of enbodiinent andupon a slightly enlarged scale for the sake of clearness.

In the drawing, Figure I is a side elevation of my combination utensilin preferred form of embodiment looking towards the flat side thereof.Fig. II is a view similar to Fig. I, but slightly in perspective,looking towards that side of 'the utensil that is opposite to the oneshown in Fig. I. Fig. III is a View corresponding to Fig. I but showingthe device in fiat form previous to its being creased or bent into thefinished article, as shown in Fig. I. Fig. IV is the reverse view of theutensil as shown in Fig. III. Fig. V is a section on the line V-'-V ofFig. I. Fig. VI is a fragmentary view corresponding to Fig. I andillustrating a modification thereof in which an apertured shani( issubstituted for the key ring. e

Referring to the numerals on the drawings, 1 indicates a key ring, whichis preferably, in the initial process of manufacture, made of temperablesteel, and which is provided upon one side with an integral plate 2,whose edge 3 is preferably in line with a diameter of the ring 1 andwhose edge 4 is preferably in line with a tangent to said ring. The ring1 and the plate 2, in the .finished article, may be finished in anypreferred style, such, for example, as in nickel plate, blue finish orplain. -The plate 2 is preferably provided next to its edge 4 with agraduated scale Ineasure, which may be, say, three inches long. Asillustrated, graduations for 21 inches are shown, the full measure 'ofthree inches being indicated upon the ring 1 in line with the edge 4. Ifpreferred, the plate 2 need not be cu-t away on the side of the edge 4,but may continue to the ring, as shown by dotted line 5 in Figs. I andIII. The ring is divided transversely, as indicated at 6, for 'thereception of the keys, or the ring may' be of the split ring form, asindicated at 7 in Fig. Il of the drawings. At its end, opposite to thering 1, the plate 2 terminates in a screw driver point 9, which alsocoperates with the wing 10 of the device to perform an additionalfunction, as hereinafter specified. The wing 10 is, in the process ofmanufacture, preferably made integral with the plate 2, and having theplanes of its opposite faces coincident with those of the plate 2. lt isalso preferably provided with a file face ll on the outside (compareFigs. II and III) and a file face 12'on the insideisee Fig. IV).

In manufacture, the plate 2 and the wing 10 being integral and made of aflat piece of metal are afterwards bent with permanent flection towardseach other, as indicated in Fig. V, along a line corresponding to theedge 3 until the opposing faces of the wing and the plate are separatedby an angle of about 35 (legrees. The file teeth on opposite sides ofthe wing 10 and upon the face 14 that in the finished article opposesthe face 12, and all other markings or cuttings, are preferably formedin the metal of the article before it is tenpered, and preferably beforethe bend along the edge 3 is formed. After that, the metal may betempered to render it hard and serviceable for use.

The file teeth on the opposing faces 12 and 14 preferably meet at anangle, as shown in Fig. IV, for the reason that the files 12 and 14constitute a pencil sharpenor, and by reason of the inclination of thefile teeth thereon, the point of the pencil when laid between thosefaces and reciprocatedor rotated is drawn towards the bottom of theangle, thereby faclitating the shaping of the point of thepencil.

v It was specified above that the screw' driver point 9 performs anadditional function. That function will now be explainedi The end of thewing 10, opposite the ring 1, terminates in a fork or bifurcation 15,which, in the finished article,'lies in close proximity to'the plate 2.The wing 10 is, however, shorter than the plate 2 and in consequence thepoint 9 of the latter extends beyond the fork 15 and affords a fulcrum,by which, when the fork is inserted under the head of a tack, the tackmay be readily pulled. The outer prong 16 of the fork 15 is preferablyshaped to constitute it a nail cleaner. The edge 17 of the screw driverpoint 9, adjacent to the fork 15, is sharpened or chamfered from itsextremity to the angle 18, where it meets the adjacent prong of the fork15 thereby forming a convenient may lie alongide of the plate and thewing, or between.

them, just as if the wing and plate were themselves members strung uponthe ring. If preferred, however the ring may be modified to a smallshank 19, as indicated in Fig. VI, which is periorated by a. key ringaperture 20, into which an ordinary key ring may be in; 5 serted. i

The Construction, purposes, and operation of my device having beenalready described in the foregoing specificaton, further reference tothem at this point is deemed to be unnecessary.

What I claim is:

1. The combination with a ring, of an integral'plate extendingtherefrom, one edge of the pinte beingin line with a diameter of thering, and the other in line with a tangent thei-eto, the tangential edgeof the plate constituting with the ring a straight edge or rule.

2. The combinationwith a ring, of an integral plate extending therfrom,one edge of the plate being in line with a' diameter of the ring, andthe other in line with a tangent thereto, the piate adjacent to thetangential edge being provided with a measure scale, indicated both uponthe plate and upon the ring.

3. In a device of the kind described, the combination` with a ring and aplate integral therewith, of a wing secured by permanent fiection at anangie to the plate, the

opposing faces of`the wing and the plate being provided with inciinedfile teeth. 4. In a device of the kind described, thcombination of aring, plate, and wing secnred by a permanent flection at an angie to theplate, the opposing faces of the wing and the plate being provided withinclined file teeth, and the onter face of the wing being provided withfile teeth.

5. The combination with a key ring provided with an eiongated piateintegral therewith, of a wing shorter than the plate secu'edthereto bypermanent fiection, and a fork upon the wing underlying the projecti'ngend of the plate, whereby said projecting end may act as a fuirum-forthe fork, suhstantially for the purpose specified.

6. The combination with an elongated plate, a win'g-` shorter than theplate Secured thereto by permanent fiection, of a fork upon the wingunderlying the projecting end of the plate, whereby said projecting endmay act as a; fuicrum to the fork, the projecting end being providedwith a sharpened edge extending from its extremity to its junetion withthe wing.

7. The combinntion with a ring and"piate projecting `from one sidethereof, of :n edge upon the piate in line with a tangent to the ring,said plate being provided with a measured rule inscribed thereonadjacentto the tangen-- tiai edge.

8. The combinaton of a pair of plates united by permanent fiection, onelonger than 'the other, the longer one te'rminating in a screw driverand the shorter in a fork one of whose pair of prongs constitutes a nailcieaner, and, in conjunqtion with the other prong and with the screwdriver point', a tack puller.

t 9. The conbination of a pair of plates united by perma nent flection,one plate being provided on the outside with a smooth face and the otherlikewise with a file face, terminating, respectively, at the bendbetween the piates, whereby a wedge shaped file is forn-ed having onesurface smooth and the other adapted to cut.

In testinony Avhereof I have hereunto signed my name in the presence' oftwo subscribing witnesses.
